Objective: To examine the expression of NGX6 gene and to investigate its association with the clinico-pathological characteristics in hepatocellular carcinoma(HCC).
Methods: Samples from 45 patients were divided into the hepatocellular carcinoma tissue group and the matched paracancerous tissue group. Reverse transcription polymerase chain reaction(RT-PCR) was used to detect the expression of NGX6 gene in the hepatocellular carcinoma and the surrounding normal tissue specimens.
Results: The positive rates of NGX6 in the hepatocellular carcinoma and the matched paracancerous tissues were 35.5%(16/45)and 77.8%(35/45), and the ratios of NGX6/G3PDH mRNA were 0.245+/-0.060 and 0.352+/-0.113.There was significant difference in the 2 groups (P<0.05). The expression of NGX6 gene was related to TNM staging (chi2=6.106,P=0.042)and lymph node metastasis(chi2=5.237,P=0.022)in hepatocellular carcinoma.
Conclusion: There is positive expression of NGX6 in the hepatocellular carcinoma and the matched paracancerous tissues. The low-expression or non-expression of NGX6 gene plays an important role in the gene transcription level in hepatocellular carcinoma.The expression of NGX6 gene is related with TNM staging and lymph node metastasis in hepatocellular carcinoma. Expression of NGX6 might be used as an early indicator of the occurrence and development of hepatocellular carcinoma.

Nasopharyngeal carcinoma‑associated gene 6 (NGX6) is associated with the Wnt/β‑catenin signaling pathway in a number of different types of cancer, including colorectal cancer (CRC). The present study is aimed to determine the functional role of NGX6 in osteosarcoma (OS) and to investigate the underlying mechanism associated with the Wnt/β‑catenin signaling pathway. NGX6 expression levels in tissues derived from patients with OS and cell lines (MG‑63, Saos‑2, U2OS and HOS) was analyzed using reverse transcription‑quantitative PCR.

Objective: To detect the expressions of nasopharyngeal carcinoma-associated gene 6 (NGX6) in nasopharyngeal carcinoma cells and tissues, and to investigate the effects of NGX6 on the proliferation and invasion of nasopharyngeal carcinoma cells and the survival of patients.
Patients And Methods: The human nasopharyngeal carcinoma cells (HONE1) and immortalized human nasopharyngeal epithelial cells (NP69) were selected and cultured. The mRNA and protein expression levels of NGX6 were detected via quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blot.

Nasopharyngeal carcinoma-associated gene 6 (NGX6) is a membrane protein primarily located in the nuclear membrane and cell membrane. Several groups reported that NGX6 gene was down-regulated in nasopharyngeal carcinoma (NPC), gastric cancer, lung cancer, liver cancer, and colorectal cancer and even less in the carcinomas with metastasis. Current studies have demonstrated that NGX6 possesses various biological functions, such as regulating protein expression of related genes, involving cell signal transduction pathways, negatively controlling cell cycle progression, inhibiting angiogenesis, and increasing the sensitivity of patients to anti-cancer drugs.
